Perennial roofs are semi-intensive green roofs with a total depth of 8-14 inches and may need irrigation, depending on the regional climate and the kind of plants used. This rooflite soil system supports taller plants that require more root space & a consistent water supply, including perennials and grasses. Because of this, perennial green roofs give you the option to create an inviting and dynamic outdoor space with more structure and color.
